Concrete posts are commonly used in many farm and agricultural applications. Portland cement and steel reinforcements are used to make these concrete posts. Production of Portland cement is responsible for a large amount of greenhouse gas (GHG) emissions and hence, use of Portland cement needs to be reduced significantly. Steel reinforcements are susceptible to corrosion. Corroded steel reinforcement swells, resulting in spalling of concrete and ultimately damaging the concrete posts. Hence, the objective of this research is to develop and test alternative concrete posts that are environmentally sustainable and not susceptible to corrosion-induced damage. Portland cement will be replaced with alternative cementitious materials such as slag and silica fume, which are industrial waste materials. These waste materials are currently dumped in the landfills, causing toxicity and other problems for the soil and people living nearby. Recycling of such waste materials will reduce GHG emissions and alleviate landfill problems. Steel reinforcements will be replaced by basalt fibre reinforcement. Basalt fibre reinforcement is corrosion resistant and slightly stronger than traditional steel reinforcement. Additionally, basalt fibre reinforcements are produced from volcanic rock called basalt and hence, basalt fibre reinforcement is an environmentally friendly material. Incorporation of industrial waste materials and basalt fibre reinforcement will make the new concrete posts environmentally sustainable and a cheaper alternative to currently used traditional concrete posts. Additionally, the state-of-the-art 3D concrete printer will also be introduced to reduce waste in concrete materials in the production of concrete posts and increase the productivity. This research will be executed by one doctoral student and two undergraduate students who will be trained in various aspects of green construction and use of 3D printing in the construction. These highly trained and skilled students will be able to bridge the skills gap in Canada. The industry partner, MEDA Engineering & Technical Services will gain a competitive edge in their business which will lead to new job creations.

混凝土柱通常用于许多农场和农业应用。波特兰水泥和钢筋用于制作这些混凝土柱。波特兰水泥的生产负责大量的温室气体（GHG）排放，因此需要大大减少波特兰水泥的使用。钢筋容易受到腐蚀。腐蚀的钢加固膨胀，导致混凝土剥落并最终破坏混凝土柱。因此，这项研究的目的是开发和测试在环境上可持续且不容易受到腐蚀引起的损害的替代混凝土柱。波特兰水泥将被替代胶合物材料（例如矿渣和硅烟）代替，这些材料是工业废料。这些废料目前被倾倒在垃圾填埋场中，造成了毒性和其他问题，对土壤和附近的人们造成了其他问题。回收这些废料将减少温室气体排放并减轻垃圾填埋场问题。钢筋将被玄武岩纤维增强剂取代。玄武岩纤维增强是耐腐蚀性的，比传统钢筋稍强。此外，玄武岩纤维增强件是由称为玄武岩的火山岩产生的，因此，玄武岩纤维增强材料是一种环保的材料。将工业废料和玄武岩纤维增强材料的纳入将使新的混凝土柱环境可持续性，并成为当前使用的传统混凝土柱的便宜替代品。此外，还将引入最先进的3D混凝土打印机，以减少混凝土柱中混凝土材料中的废物，并提高生产率。这项研究将由一名博士生和两名本科生执行，他们将在绿色建筑的各个方面接受培训，并在建筑中使用3D打印。这些训练有素且熟练的学生将能够弥合加拿大的技能差距。行业合作伙伴，MEDA工程和技术服务将在其业务中获得竞争优势，这将导致新的工作创造。
